Getting activation code for an old Turbotax

[nc001]

I need activation code for 2020 for an amendment

When I tried to install it, it tells me that all available activations have been used. I guess because over the years I installed 2020 in different computers for the purpose of checking my old taxes and compare them to the new ones.

Where can I get or buy a code just to use it once more for this ammendment?

Well you can buy 2020 here.  You will need to have the data file ending in .tax2020 on your computer.  Or call in and ask if they can give you a new code.
